Abstract
A találmány tárgya extruziós berendezés nem ömleszthető vagy nemfolyékony műanyagok visszanyerésére extrudercsigával (4) rendelkezőextruderrel (1), egy bevezető berendezéssel (3), amely egy tölcsér (2)révén a formamasszát az extrudercsiga (4) extruder töltési zónájába(7) továbbítja, ahol a bevezető berendezés (3) mint bevezető csiga vankialakítva. A találmány lényege a következő: a) a bevezető berendezés(3) mint kettős csiga (5, 6) van kialakítva, b) mindegyik csiga (5, 6)tengelye (X-X) az extrudercsiga (4) tengelyéhez (Y-Y) képest magasságiirányban el van tolva c) a kettős csiga (5, 6) csigateknője (12) azextrudercsiga (4) extruderhengerének (14) a csigateknő (12)szélességéhez igazított nyílásába torkollik, d) az extrudercsiga (4) atöltési zóna (7) tartományában több menetesen van kialakítva, e) azextrudercsiga (4) a töltési zóna (7) tartományában 1 D-nél nagyobbemelkedésű f) a csigák (5) csigatengelyei (10) az átadó tartományban(11) dekompresszív kialakításúak.
